Somebody can tell me what SG are thie three Mauritius?






Thanks

Fakes, one presumes.

GeoffHa, sorry im not asking for the autheticity of the stamps. Two of them are verified for two experts, and the blue one have Certificate of the Royal Philatelic Society London, with four sings.
I prefer, if somebody dont know, dont answer. Im asking what SG are, because im shure in blue one, the certificate tell is SG22, but im not shure the others two, because the experts are not shure, I would like to know, before I certificate.
Sorry for my answer, but is the second time somebody tell me very fast one of my stamps is a fake, and is not true.
Thanks.

Astrakov, they look like SG16 or SG17, SG's "Type D", but in a worn state. I can't see any evidence of blueing of the paper, but this may be because they are scanned with a blue background. The design is too worn for them to be Types "A" to "C" but not worn enough for the very last issues "Type "E". Good luck with the expertising. T

Very very thanks Tim H, ill try to expertise, to know the SG and Type. I have more british and commonwealth clasics stamps, and im trying to identify to arrange and maybe after sell, to continue with my collection.
Thanks again.
